For Chari and Sri, the alternative to digging would have to be radio, and while drinking beer and poring over dense technical books, they came across a radio technology developed in the 1970s for military uses. The technology worked on battlefields, but its inventors and the engineers who came after assumed that it wouldn't scale. Sri and Chari thought otherwise. They suspected that if you could program the nodes of these radio networks cleverly enough, teaching them to move information around quickly, you could make the network as big as you wanted.
Their idea was a variation on the principle of the bucket brigade or steppingstones. If you can't get the signal to reach all the way to the wired Internet, make it hop from one transmitter to another until it does. And give it some basic rules for finding the most efficient pathway there.
Here at Ritual, for instance, e-mail data comes in over wires to a base station or router somewhere in the room and then heads through the air to the nearby laptop. Everyone in the café is just one hop from the wired Net. This configuration requires every user to be within about 100 feet of the device that's plugged in, and it's why wireless broadband is generally limited to offices and cafés. But what if you told that router to select another router for passing along its message, and told that router to select yet another after that? If you taught those routers to make efficient choices that wouldn't require arduous processing, eventually the Internet would spill out into the streets.
Sri and Chari got hold of some Wi-Fi gear--a cheap type of radio technology recently introduced to the enterprise market for office environments--and started playing with their routing ideas. They mounted antennas on cars and tooled around Cambridge, testing the performance of nodes programmed to obey their new steppingstone rules. "When we started doing this," Chari says, "people laughed at us, saying Wi-Fi is an indoor technology. But our approach has always been, don't take anyone's word for it."
The two men soon realized that they were no longer solving a math problem: They were developing a product. So they picked up and left Boston for northern California. They hooked up with two friends of friends who understood finance and formed a company. It was not a particularly opportune time. "In 2001, we were out there looking for funding. It was awful," says Chari. But Bill Gurley, whose firm, Benchmark Capital, invested early in companies such as eBay and Red Hat, liked their ideas. "I don't think anyone at that time was thinking about municipal wireless," Gurley recalls. "But what was keeping Wi-Fi from going outside?"
Even in the united states, More than a third of Internet users in exurban or rural areas can get only dial-up connections.
Well, nothing. In the United States, most towns already own the infrastructure for suspending 14-pound boxes in the sky: lampposts, traffic lights, telephone poles, city buildings. The Tropos routers themselves cost only about $3,500 each. So with 30 per square mile installed in a city like San Francisco, you'd spend about $5 million on boxes to serve more than 700,000 citizens. According to a report by PricewaterhouseCoopers, building a fiber network costs $2,000 "per home passed," in the industry's argot; providing DSL costs a few hundred dollars. Compare both with Philadelphia's estimate that the cost per home passed of its Wi-Fi network will be $30. On the user end of the equation, the hardware economics look even better. The Wi-Fi cards that early adopters were sliding into their laptops in 1999 went for about $2,000 apiece. Today the devices are preloaded into nearly all new computers and cost less than $10 each. Right now, as Chari and Sri drain their lattes at Ritual, there are an estimated 50 million Wi-Fi-ready computers out there.
So Bill Gurley got onboard. He liked the open standards of Wi-Fi technology and how quickly the price on the user's side was dropping. He loved Chari and Sri's vision of teaching routers with limited range and capacity how to build bucket brigades and choose the most promising pathways, based on the condition of the network. "It's very elegant," Gurley says. He also liked the growth potential of the market and the focus on software. "As a venture capitalist, I love everything about the Tropos model," he says.
In January 2002, Benchmark Capital ponied up $2.2 million for the young company to work with. Other VC firms followed, including the Intel Communications Fund and Siemens Venture Capital. And so did Ron Sege.
Good Enough Beats Best
Ron Sege (pronounced seh-gee) is a tall stick of a guy with blue eyes and blond eyelashes, whose elaborately stitched jeans were meant for a younger man. At 49, he is on his second wife, his second batch of kids, and the fourth small company he intends to make large. In a sense, Sege is a Web 2.0 guy all around, bringing hard-earned experience to a young company with a still-unproven business model. As he puts it, "I've seen this movie before."
Sege began working in technology in the 1980s, but really hit his stride in the '90s, as a manager at 3Com, the company that spawned Ethernet technology. 3Com had a few hundred employees when he arrived; by the time he left in 1998, he had 4,000 employees under his leadership alone. He learned a lot about growth in his 10 years at 3Com, but more interesting was what he learned about the power of lowering your standards. "From a tech perspective, good enough beats best," he says. Ethernet, the protocol that allows office PCs to share databases and printers and storage in a small local network, was far from perfect. "But it was inexpensive, easy to use, and anybody could design to it." Sege learned the beauty of this approach to business--float a quick and dirty product, let users and other product developers improve on it, and push it as a dominant shared platform. "Wi-Fi has many of the same attributes," he says.
After 3Com, Sege took a job as executive vice president of Lycos, one of the first Internet portals, where he helped engineer an Internet-bubble buying spree that included acquisitions of Matchmaker.com, Quote.com, and Wired Digital. "That was my media mogul period," Sege says with a laugh. He left Lycos in 2001 and joined Ellacoya Networks, a company based in Merrimack, New Hampshire, that creates software to help broadband providers ease congestion in their networks.
